ICF: Inertial Confinement Fusion
MCF: Magnetic Confinement Fusion
CFS is Commonwealth Fusion Systems - https://cfs.energy/
Q is the ratio between energy in and out in a fusion system. Q > 1 is the holy grail, which implies we have more energy out of the fusion system than in. CFS is aiming for Q 11 in its prototype reactor.
SPARC is the "Smallest Possible" ARC I believe. It's their prototype reactor that they're working on that uses magnetic fields through superconductors to contain Hydrogen as it heats up into plasma and goes through the fusion process.
ARC is the 400MW reactor that will be produced (aimed for within a decade) if SPARC succeeds - it's the scaled-out version of SPARC.
It has an impressive set of people working on it (ex-SpaceX).
And yes, ARC is named after the Iron Man reactor.

Substack to keep it simple. But I'm not extremely happy with the design.

These are company reported base salaries for OpenAI members of technical staff. The base salaries look very similar to standard tech bands.
They could be underpaying immigrants, but that's unlikely, given that it's illegal and they have a lot of attention on them.

That's too expensive. I'd prefer a monthly/yearly fee.

Thank you!

Yeah, large-scale systems are often boring in my experience, because the scale limits what features you can add to make things better. Each and every decision has to take scale into account, and it's tricky to try experimenting.
I think it has to do with the kind of engineer you are. Some engineers love iterating and improving such systems to be more efficient, more scalable, etc. But it can be limiting due to the slower release cycles, hyper focus on availability, and other necessary constraints.

Does anyone know which tool can be used to make such visualizations?

To clarify, the slow git push was likely custom pre-receive hooks being slow.

I remember we migrated 2+ million LoC to being formatted by Black at Dropbox.
Our Livegrep instance with a custom Git blame implementation always crashed at the commit made to do the migration :-) We had to pause our merge queue because we didn't want to run into conflicts, and I remember the `git push` ended up taking a while.
There was only one change that we had to make to Black to get it working on our codebase - https://github.com/psf/black/commit/024c9cab55da7bd3236fd887...
Glad to see it's now stable.
